Lighting finding after a week

[shawn101]

I would like to report my leo much prefers the dark blue Exoterra night heat bulb I got over the infrared much brighter light. The dark blue is just enough light to see her at night when she is out and doesn't bother as much as the infrared seemed to.

I suspect just because people say they can't see red, doesn't mean they can't detect the light. It would be like me putting a red light in a room and making the outside windows blue. The light would appear purple in the visible light range.

I don't suspect a gecko sees in the infrared longer wave lengths, but I read, and based on the change in light, that they may see in a UV range which is a very short wavelength. The dark blue light is a shorter wavelength than the red and may be preferable.

I also had my gecko on me in the kitchen the other day and used the microwave. She immediately freaked. Microwaves emit longer wave radiation than infrared, the screen mesh in the front stops the waves from leaving the front. I don't know what kind of energy leaves a microwave if any. May have been just the sound that scared her, maybe a combo.

Hi,

This reminds me of the mistake I made years ago. Well, I bought this

bulbhttp://www.zoomed.com/db/products/EntryDetail.php?EntryID=122&DatabaseID=2&SearchID=1

and one of my leos was bothered. Suddenly it struck me, physics, what was I thinking. Over time we become rusty and forget part of what we learned. Infrared is referring to the electromagnetic radiation with longer wavelengths.

The bulb is red glass, and it also states Very little visible light. It was one of those moments as they say "duh". :biggrin:

Probably inferring little vis light to the reptile, we see a lot of red at the close end of the infrared spectrum.

If i had the means I would propose an experiment of a tank of crickets on one side of my terrarium with crickets dusted with a powder that glows with UV coating and a dim UV light over top and on the other side a tank of crickets with infrared and to see which side the gecko would be attracted to to try and eat the crickets.

I suppose even with a dim UV light you could release dusted UV crickets and non-dusted UV crickets and see which the gecko goes for the majority of the time.
